Smittia porifcra (Smitt). 



Osburn, 1912, p. 245. 



Taken with some frequency at Crab Ledge, in 17 

 fathoms, and at Great Round Shoal fishing 

 ground, on shells and on the stems of hydroids 

 and Boltenia. 



Porella propinqua (Smitt). 

 Osburn, 1912, p. 248. 



Crab Ledge, and off Sankaty Head, not uncom- 

 mon on shells and hydroid stems. 



Porella acutirostris Smitt. 



Osburn, 1912, p. 248. 



Taken by the Survey on various occasions at 

 Crab Ledge and at Great Round Shoal fishing 

 ground, incrusting shells and pebbles; com- 

 mon. 



Porella concinna (Busk). 

 Osburn, 1912, p. 247. 



Crab Ledge, incrusting stones and shells, 14 to 

 20 fathoms; not common. 



Porella proboscidea Hincks. ., 



Osburn, 1912, p. 249. 



Taken in abundance at Crab Ledge, Great Round 

 Shoal, and off Sankaty Head ESE., in 23 

 fathoms; also at Nantucket Shoals. 

 Rhamphostomclla bilaminata (Hincks). 



? Verrill and Smith, 1873, p. 714, 419 (Cellepora 

 scabra a ); Osburn, 1912, p. 244. 



Vineyard Sound and Quicks Hole.? Verrill. 

 Taken by the Survey at several points in Vine- 

 yard Sound and Buzzards Bay; common at 

 Crab Ledge, in 14 to 21 fathoms, on hydroid 

 stems; Great Round Shoal fishing ground, in 

 8 fathoms. 



Fish Hawk stations: 7743, 7745; Phalarope 



station i. 

 Rhamp hos lamella coslala Lorenz. 



Osburn, 1912, p. 244. 



Thus far only recorded from two outlying points, 

 Crab Ledge (common) and Great Round Shoal 

 (scarce), in company with the preceding 

 species. 

 Rhamphostomella ovata (Smitt). 



Osburn, 1912, p. 245. 



Vineyard Sound, 1875, one well-developed col- 

 ony on shell of Modiolus modiolus; Crab Ledge, 

 August 12, 1909, a few small colonies. 



Family FLUSTRELLID^. 



Flustrella hispida (Fabricius). 



Verrill and Smith, 1873, p. 708, 312, etc. (Alcy- 

 onidium hispidum)', Davenport, 1891, p. 49; 

 Osburn, 1912, p. 250. 



Woods Hole Harbor, on Ascophyllum beds, abun- 

 dant; Tarpaulin Cove; Cedar Tree Neck; Rob- 

 insons Hole. Locally very abundant, incrust- 

 ing Fucus and Ascophyllum, at low water 

 mark; less commonly found upon rocks, or 

 other objects; not recorded, however, from 

 dredging stations. 



Family ALCYONIDIID/E. 

 Akyonidium uerrilli Osburn. 



Verrill, 1872, p. 289 (Akyonidium ramosum); 

 Verrill and Smith, 1873, p. 708, 404, etc. 

 (Akyonidium ramosum); Osburn, 1912, p. 252 

 (nom. nov.). 



Eastward to Vineyard Sound, "often very abun- 

 dant, attached to rocks in shallow water. ' ' Ver- 

 rill. This species is rare in the waters dredged 

 by the survey, having been taken in only one 

 locality, Phalarope station 37, at Sow and Pigs 

 Reef, where two small specimens were found. 



The Cellepora scabra of Smitt has been separated into several species, of which two are herewith recorded. While it is 

 impossible to identify Verrill's record with certainty, it seems probable that he referred to the present species, rather than 

 to the following, which is less common and has not been taken in the inner waters of the Sound.
